Ok so iv got a cylinder 3 misfire code up and you can feel the misfire but the catch is its only at idle... one you give it gas and it goes above 1k rpm there is no sign of a misfire no sputtering nothing. The plugs are new the icm is new the coil that leads to 3 and 6 is new I have also switched around plug wires and injectors could it still be a wire cuz I was told they are different lengths and that could mess with it?
